Closed-loop electronic controller for applying transmission friction clutches |
摘要 |
A torque-based clutch engagement controller for achieving smooth friction clutch engagement in a multiple-ratio transmission for an automotive vehicle driveline comprising a torque measuring circuit that determines torque inputs for the controller as a function of measured engine torque and turbine acceleration, means for determining the torque commanded by the vehicle operator as a function of engine throttle position, means for comparing the desired torque commanded by the operator to the input torque values, and means for converting the torque values to a pressure value as a function of the difference between the desired torque and the input torque whereby the pressure developed by the system applies a friction clutch so that engagement of the clutch occurs rapidly with optimum smoothness. |
